When we create an XSLT transformation, we need to state the version and encoding b of the XML. The XSLT namespace c needs to be specified. The namespace gives the document the rules and specifications that it is expected to follow. The

cascade="none", the default, tells Hibernate to ignore the association. cascade="save-update" tells Hibernate to navigate the association when the transaction is committed and when an object is passed to save() or update() and save newly instantiated transient instances and persist changes to

To set up a message-driven EJB to receive JMS messages, you need to describe its functionality in the XML deployment descriptor. For instance, the sample XML in listing 1.10 describes the message-driven bean, including which JMS topic it describes.

Before you assign values to array elements, or retrieve those elements, you must declare and size the array for your needs. The Dim statement creates an array just as it does ordinary variables; the ReDim statement resizes an array after it already exists.

9.6 Summary

An MDB can chew on only one message at a time. Until its onMessage() method returns (swallows what s in its mouth), an MDB cannot be used to handle other messages. That is, an MDB instance is not re-entrant. If another message is delivered to the MDB container before a busy instance s onMessage() method returns, then the container will pluck another MDB instance from the instance pool to handle the new message. This is true for both publish/subscribe and point-to-point messaging. Messages published to a topic are delivered to one MDB instance in every MDB container registering interest in the topic. Messages sent to a queue are delivered to one MDB instance in exactly one MDB container registering interest in the queue. In either case, an MDB instance can only handle messages serially. When the onMessage() method takes a relatively long time to handle a message, more and more instances in an MDB instance pool will be needed to handle high message volumes. Messages will start to back up any time the average arrival time of messages is greater than the average time to consume each message, thereby creating a bottleneck that restricts message throughput. In general, anytime the ratio of message production to consumption is high, message throughput will suffer.
